Receiving voice input within a notification

In this section, we will be taking a look at how we can use notifications that can allow the user to respond to these by simply using their voice. Since Android wearable devices don't contain a keyboard, a user can swipe on a notification and respond to the action using their voice, or simply by choosing from a list of options presented to them, and tapping on the item right from their Android wearable device.

To receive voice input within a notification, perform the following steps:

1. Open the MainActivity.java file from within the Project Navigator window.
2. Modify the onCreate(Bundle savedInstanceState) method and add the following highlighted code:

   @Override
       protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);
   
           // Clear all previous notifications and
           // generate new unique ids
           NotificationManagerCompat.from(this).cancelAll(...
